ER4043 0.030" 1lb - Aluminum MIG Welding Wire

PGN Aluminum MIG Welding Wire - ER4043-0.030 Inch, 1 Pound Spool - Aluminum MIG Wire with Silicon for Puddle Fluidity and Enhanced Weld Durability - For All Position Gas Welding We set out to create a solid MIG wire that worked beautifully with aluminum alloys. MIG welding wire with an arc you could control, penetration that inspired confidence, and low splatter that kept cleaning to a minimum and aesthetics to the max. And we did just that. Meet the PGN ER4043 welding wire. It creates smooth welds on 6061, 6063, 5052, 3004, 3003 and cast alloys 356.0, 357.0, 413.0, and 443.0. A 5% silicon content increases puddle fluidity for easier welding and crack-resistance for better durability. We go the extra mile by diligently packing our MIG welder wire in moisture-resistant film - something others don’t. This means wire that’s rust-free, has no tangles, and gives you no issues when feeding it into your welder. Whether you’re tackling a client’s project, performing repairs in the garage
